Changing Climate Exacerbating the Hay Fever
Warns Blueair, a world leader in indoor air purification technologies designed to remove airborne contaminants.
For tens of millions of people around the world from Los Angeles to Delhi, London to Beijing the annual changes in season bring an onslaught of itchy eyes, wheezing, sneezing, and other symptoms sparked by ‘allergic rhinitis’. And the torments are being exacerbated by global warming, which is causing plants to generate more pollen than before, helping invasive weeds to spread and extending pollen seasons, warns Blueair, a world leader in indoor air purification technologies designed to remove airborne contaminants.
“There is now convincing scientific evidence that climate change is spurring increased pollen concentrations, resulting in increased allergen exposure and ever-more allergy sufferers,” said Bengt Rittri, founder and CEO of Blueair. Mr. Rittri said growing allergic rhinitis rates highlight the need for people to be made aware that they can alleviate the problem using indoor air purifiers with hepa air filters at home or in the workplace to create safer indoor havens.
The World Allergy Organisation (WAO), an international alliance of 97 regional and national allergy, asthma and immunology societies, says allergies such as hay fever are increasing in prevalence and severity and will continue to be a concern as temperatures rise and exposures increase.
Over 400 million people around the world are estimated to suffer from the misery caused by allergic rhinitis. In the United States, it affects between 10 to 30 percent of the population and up to 40 percent of children and causes direct medical costs that increased from US$6.1 billion in 2000 to US$11.2 billion in 2005, a greater toll than diabetes, coronary heart diseases and asthma, according to WAO.
